Computational Fluid Dynamics: a Technique to Solve Complex Biomedical Engineering Problems - a Review
Authors: , , ,
Abstract: Fluid flows play a major role in everyday life, such as thunderstorms, environmental disasters, in engineering fields, applied biosciences to understand complex processes such as blood flow, breathing and renal flow in living systems. Understanding of flow physics is important to execute detailed engineering and healthcare product development. Mathematical modelling can solve the physics of fluid dynamics using partial differential equations (PDE) built on conservation laws. This model can be solved numerically by Computational Fluid Dynamics (CFD) to yield quantitative results. CFD has attracted significant interest in the biomedical engineering area, from researchers to study the complex human anatomical and physiological processes, response to diseases and its effectiveness to develop prosthetics. The introductory sections of the review explain the basics of CFD and its use in biomedical engineering research. The review then focuses on the applications of CFD in biomedical problems, including cardiovascular diseases, airflow pattern and aerosol deposition in lungs, cerebrospinal fluid flow in brain and for artificial organ design analysis. The widespread adoption of CFD will dramatically accelerate the improvement of healthcare soon with patient specific customization. Moreover, contextual evidence is also provided for beginners to better understand of the topic.
